Not likely to work. Part of the reason is the TDM card essentially answers a call when ringing occurs. That "answer" essentially closes the tip-ring loop to the pstn (central office), and the central office will interpret that as a change in line status. The central office will not forward any more digits (dial pulse or dtmf) when that occurs. If the TDM card supported E&M signaling, then one would have the signaling structure (to the central office) to support the wanted DID function; but that doesn't exist and the TDM chipset doesn't support E&M. Last, the asterisk code would need to change in such a way as to listen for additional dtmf digits _after_ the TDM card closed the tip-ring loop, and I believe that code doesn't exist either. (Even if the code did exist, then what method would be used to signify to the central office that a call was answered by an asterisk phone?) Bottom line... not with a TDM card. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
